In a Tweet shared just this afternoon, Pwn20wnd reveals that the somewhat minor update addresses an issue involving the voucher_swap exploit by Brandon Azad on certain beta-centric firmware versions on A12(X) devices:

Here’s the official changelog for unc0ver v3.0.0 beta 45 as
per the GitHub repository:

03/11/2019 – v3.0.0~b45 was released for public testing with the following changes:

– Fix the voucher_swap exploit for the beta firmwares on A12-A12X

– Update the APT lists cache file for repositories

It’s
worth noting that the unc0ver v3.0.0 pre-release is still a beta, and while it
might be tempting to hop onboard right now, we’d strongly advise waiting for the
official public release to prevent any possible bugs from manifesting.

These
‘partial’ support releases are really only intended for developers, and allow
them to prepare tweaks to support iOS 12. Users will get the most benefit from
their jailbreak when Cydia and Cydia Substrate are added in the future.

Those
already jailbroken on iOS 12 with the unc0ver v3.0.0
pre-release are being advised to download and run this update as soon as
possible to take full advantage of the new features and improvements.

The
latest public release of the unc0ver jailbreak tool is v2.2.6 with support for
iOS 11.0-11.4 beta 4 – the unc0ver v3.0.0 pre-release is the only iteration
that supports iOS 11.4-11.4.1. Both versions of the unc0ver jailbreak tool can be had from Pwn20wnd’s official GitHub repository.
